Thanks so much for such an important and useful piece of information!
Really appreciate your help!

I think we will be able to use RHEL 6 on our server as nothing has
been configured on RHEL 5.5 yet! Thanks for that RPM link for postfix
as well, will be handy if something stops us from reinstalling rhel 6
on the new server.

God bless!
